[Bug fortran/34657] New: program-unit MY_SUB imports symbol MY_SUB

[jv244 at cam dot ac dot uk]

The following is non-standard and the compiler should probably generate a
warning/error with '-pedantic -std=f95', but does not do so with
gcc version 4.3.0 20080103 (experimental) [trunk revision 131300] (GCC)

module test_mod
interface
  subroutine my_sub (a)
    real a
  end subroutine
end interface
end module

subroutine my_sub (a)
  use test_mod
  real a
  print *, a
end subroutine

END

[Bug fortran/34657] program-unit MY_SUB imports symbol MY_SUB

[burnus at gcc dot gnu dot org]

------- Comment #1 from burnus at gcc dot gnu dot org  2008-01-04 07:29 -------
NAG f95 and g95 print an error:
  Error: USE TEST_MOD in program-unit MY_SUB imports symbol MY_SUB
  Error: Module 'test_mod' at (1) redefines the current program unit 'my_sub'

ifort prints nothing by default and with -stand f95:
  Warning: An interface-block in a subprogram shall not contain an
interface-body for a procedure defined by that subprogram.   [MY_SUB]
